Public Records
R.C. 149.43 states in pertinent part:
“(A) As used in this section:
“(1) ‘Public record’ means any record that is kept by any public office, including, but not limited to, state, county, city, village, township, and school district units, except medical records, records pertaining to adoption, probation, and parole proceedings, records pertaining to actions under section 2151.85 of the Revised Code and to appeals of actions arising under that section, records listed in division (A) of section 3107.42 of the Revised Code, trial preparation records, confidential law enforcement investigatory records, and records the release of which is prohibited by state or federal law.
“(2) ‘Confidential law enforcement investigatory record’ means any record that pertains to a law enforcement matter of a criminal, quasi-criminal, civil, or administrative nature, but only to the extent that the release of the record would create a high probability of disclosure of any of the following:
U # * *
“(c) Specific confidential investigatory techniques or procedures or specific investigatory work product[.]
« * * *
“(4) ‘Trial preparation record’ means any record that contains information that is specifically compiled in reasonable anticipation of, or in defense of, a civil or criminal action or proceeding, including the independent thought processes and personal trial preparation of an attorney.
“(B) All public records shall be promptly prepared and made available for inspection to any person at all reasonable times during regular business hours. Upon request, a person responsible for public records shall make copies available at cost, within a reasonable period of time. In order to facilitate broader access to public records, governmental units shall maintain *501public records in such a manner that they can be made available for inspection in accordance with this division.”
R.C. 4117.17 states:
“Formal charges, petitions, complaints, orders, evidence, fact-finding recommendations, and other proceedings instituted by the state employment relations board under Chapter 4117. of the Revised Code are public records and available for inspection or copying subject to rules made by the board. All hearings on complaints or petitions pursuant to Chapter 4117. of the Revised Code are open to the public.”
Appellants argue that R.C. 4117.17 rather than R.C. 149.43 governs access to SERB’s files. They contend that R.C. 4117.17 is a specific statute covering the same subject matter as R.C. 149.43 and therefore prevails over the latter, more general statute.
R.C. 1.51 states:
“If a general provision conflicts with a special or local provision, they shall be construed, if possible, so that effect is given to both. If the conflict between the provisions is irreconcilable, the special or local provision prevails as an exception to the general provision, unless the general provision is the later adoption and the manifest intent is that the general provision prevail.”
As R.C. 1.51 states, if there is a conflict and the statutes cannot be construed to give effect to both, the special provision ordinarily prevails. We, however, find no conflict between the statutes in question. R.C. 149.43 provides a broad definition of public records. R.C. 4117.17 provides specific direction when a request for SERB’s records is made. For example, there can be no question now, as there may have been prior to the enactment of R.C. 4117.17, that the specifically designated categories in R.C. 4117.17 constitute public records. However, R.C. 149.43 must be applied to SERB’s records not specifically designated in R.C. 4117.17 and to exceptions such as “trial preparation” materials and confidential law enforcement investigatory records. Effect may be given to both statutes because a determination of whether certain of SERB’s records are public begins with R.C. 4117.17. If there remains a question, R.C. 149.43 must be applied. We must assume that had the General Assembly intended R.C. 4117.17 to be exclusive of other public records statutes, one or both of the statutes would reflect that intention.
The first question, therefore, is whether the records listed in R.C. 4117.17 include SERB’s investigatory files. Two references in the statute are applicable — “evidence” and “other proceedings instituted.”
*502It is clear by the terms of R.C. 4117.12(B) that when a charge is filed with SERB, the purpose of SERB’S investigation is to gather evidence that tends to prove or disprove the charge. Based on the evidence before it, SERB initially determines whether there exists probable cause upon which to issue a complaint. While there may be material in SERB’S investigatory file that is not evidence and not available to the public, that material may be redacted by a trial judge after an in camera inspection of the files. All evidence in the files that is not excepted under R.C. 149.43 must be disclosed, as “evidence” is a category specifically designated in R.C. 4117.17.
R.C. 4117.17 also states that “other proceedings instituted” by SERB are public. Appellants’ assertion that the General Assembly intended to exclude items not specifically listed is unsupported and without merit. The clear language of the statute demonstrates that the General Assembly intended a policy of openness for proceedings by SERB. Investigatory files are therefore not implicitly excluded under this language and, unless excepted from disclosure, are public records under R.C. 149.43.
As stated supra, “evidence” in SERB’S investigatory files must be disclosed. Pursuant to R.C. 149.43, the balance of the information in SERB’S investigatory files must also be disclosed unless the material is specifically excepted, because such files constitute a record kept by a public office. Appellants claim the file is excepted under R.C. 149.43. An analysis of the exceptions under that statute is therefore required.
SERB argues that the records need not be disclosed because (1) SERB’S unfair labor practice investigatory file consists of “trial preparation records” as the term is used in R.C. 149.43(A)(4), and (2) SERB’S file is a “confidential law enforcement investigatory record” under R.C. 149.43(A)(2), the release of which would disclose confidential information.
“A governmental body refusing to release records has the burden of proving that the records are excepted from disclosure by R.C. 149.43.” State, ex rel. Natl. Broadcasting Co., v. Cleveland (1988), 38 Ohio St.3d 79, 526 N.E.2d 786, paragraph two of the syllabus.
Material cannot be excepted from disclosure simply by an agency’s broad assertion that it constitutes trial preparation records. For the trial preparation exception to apply, the records must have been “specifically compiled in reasonable anticipation” of litigation. R.C. 149.43(A)(4). We have previously held that when an investigation has multiple purposes, the records of that investigation cannot be said to be trial preparation records. See State, ex rel. Coleman, v. Cincinnati (1991), 57 Ohio St.3d 83, 566 N.E.2d 151; State, ex rel. Zuern, v. Leis (1990), 56 Ohio St.3d 20, 564 N.E.2d 81.
There is nothing in the record to suggest that SERB’S files meet the burden required to except them from disclosure. As stated in State, ex rel. Natl. *503Broadcasting Co., v. Cleveland, supra, the burden is on SERB to demonstrate that the records fall within the claimed exclusion. R.C. 4117.12(B) requires that when a charge alleging an unfair labor practice is filed, SERB shall “investigate the charge,” and if there is probable cause for believing a violation has occurred, it “shall issue a complaint and shall conduct a hearing concerning the charge. * * * ” If probable cause is not found, SERB will dismiss the complaint. See R.C. 4117.12(B). In fact, in addressing a different issue, SERB itself argues in its brief, “[t]he investigatory file is used by SERB in determining probable cause. Probable cause was determined on November 25, 1987. * * * After SERB’S probable cause determination, the case thereafter proceeds on a blank slate. The only evidence SERB considers when determining the merits of a case is that which is introduced at the public hearing. * * * ” This investigative process cannot be said to be “specifically compiled in reasonable anticipation” of litigation as described in R.C. 149.-43(A)(4). Only after probable cause has been found in SERB’S initial investigation, and it determines that a complaint shall issue, can further compilation of information arguably be deemed to be in reasonable anticipation of litigation. The decision to prosecute is not an adjudication. Ohio Assn. of Pub. School Emp., Chapter 643, AFSCME, AFL-CIO v. Dayton City School Dist. Bd. of Edn. (1991), 59 Ohio St.3d 159, 572 N.E.2d 80.
The first anticipated litigation is the hearing on the complaint before SERB’S hearing officer. As the burden is on SERB to demonstrate the applicability of the trial preparation exception, it is free to submit the records to the trial court for an in camera scrutiny rather than turn them over directly to the sheriff. State, ex rel. Natl. Broadcasting Co., v. Cleveland, supra. Investigatory files compiled by SERB pursuant to R.C. 4117.12 must be disclosed upon request pursuant to R.C. 4117.17 and 149.43 unless an in camera inspection demonstrates that all or any portions of the files are excepted from disclosure. Excepted information may be redacted prior to disclosure. The same standard must be applied to appellants’ claim that the material constitutes “confidential law enforcement investigatory records” excepted from disclosure.
SERB argues that disclosure of its records will necessarily reveal its specific confidential investigatory techniques “designed to ferret out information” by way of strategies “similar to a deft cross-examination.” While this may be true, it is not for this court to decide. The purpose of an in camera inspection by the trial judge is to determine whether such confidential techniques would be revealed. Neither this court nor any other court can determine whether confidential information will be revealed without an examination of that information.
*504Appellants also argue that the sheriff failed to preserve the public records issue for review on appeal. They contend that the only request for the records was made by the sheriffs counsel in an oral motion to the hearing officer to compel the Attorney General, SERB’s counsel, to produce the documents. Appellants maintain that because there was no specific request of SERB to produce the records, a proper request to the “person responsible” for the records under R.C. 149.43(B) was not made. Contrary to this argument, the sheriff did make a proper request for the documents. The request was made to SERB’s counsel, the Attorney General. R.C. 149.43(B) states that “[u]pon request, a person responsible for public records shall make copies available at cost, within a reasonable period of time. * * * ” As SERB was represented by counsel, the sheriff’s request for the public records from SERB’s counsel was proper. No specific form of request is required by R.C. 149.43.
Finally, appellant SERB contends that because the sheriff was not prejudiced by SERB’s failure to produce the investigatory file, the court of appeals erred in ordering the trial court to conduct an in camera inspection of the records. This argument also must fail. There is no way to determine whether the sheriff has been prejudiced, because the files have never been viewed by the sheriff or by a court.

Remand
SERB’s order of December 22, 1988 required the sheriff to, inter alia:
“A. Cease and desist from:
U * * *
“(2) Discriminating in regard to hire or tenure of employment or any term or condition of employment on the basis of the exercise of rights guaranteed by Chapter 4117 of the Revised Code. Nothing precludes any employer from making and enforcing an agreement pursuant to Division (D) of Section 4117.09 of the Revised Code.”
In its February 24, 1989 judgment entry, the trial court ordered: “The Motion by SERB to take additional evidence on the revocation of the auxiliary commissions after SERB’s ruling was issued, is sustained. The matter is referred back to SERB to take new evidence on the January, 1989 Sheriff’s Department’s revocation or failure to renew auxiliary commissions held by Deputy Is employed by the Sheriff’s Department. * * * ”
The court of appeals determined that the trial court impermissibly expanded its scope of authority in ordering the remand. R.C. 4117.13(B) provides:
*505“The findings of the board as to the facts, if supported by substantial evidence, on the record as a whole, are conclusive. If either party applies to the court for leave to adduce additional evidence and shows to the satisfaction of the court that the additional evidence is material and that there exist reasonable grounds for the failure to adduce the evidence in the hearing before the board, its member or agent, the court may order the board, its member, or agent to take the additional evidence, and make it a part of the transcript. The board may modify its findings as to the facts, or make new findings, by reason of additional evidence so taken and filed, and it shall file the modified or new findings, which, if supported by the evidence, are conclusive and shall file its recommendations, if any, for the modifying or setting aside of its original order.”
The court of appeals determined that the additional evidence to be taken by SERB upon the trial court’s remand was not material to SERB’S December 22, 1988 order because the evidence did not concern the propriety of the initial order, but addressed only whether the sheriff was violating the initial order.
SERB’S initial order did cover the issue that was to be addressed on remand as is demonstrated in the portions of SERB’S December 22,1988 order quoted supra. The court of appeals correctly determined that SERB’S December 22 order dealt with the revocation of three auxiliary commissions. But the order also proscribes continuing conduct of the sheriff regarding terms of employment of his deputies.
Moreover, we find no basis for the sheriff’s argument that post-order conduct is not a proper ground for remand under R.C. 4117.13(B). Under the statute, there need only be “reasonable grounds” for the failure to adduce the evidence in the original hearing. The nonexistence of evidence is a reasonable ground for failing to produce the evidence at the first hearing. The conduct at issue was material to SERB’S order directing the sheriff to cease and desist from “[discriminating in regard to * * * any term or condition of employment on the basis of the exercise of rights guaranteed by Chapter 4117 of the Revised Code.” On remand, SERB found that the sheriff’s refusal to renew auxiliary commissions violated its previous order. Pursuant to R.C. 4117.-13(B), it is within the trial court’s discretion to remand a case to SERB to take additional evidence regarding a violation of the order being appealed.
Ill
Unfair Labor Practices
The court of appeals reversed the judgment of the trial court, holding that it “abused its discretion in finding the [December 1988] order to be supported by substantial evidence on the record as a whole.”
*506The proper standard to be applied by the trial court in reviewing a decision by SERB was stated by this court in Lorain City Bd. of Edn. v. State Emp. Relations Bd. (1988), 40 Ohio St.3d 257, 260, 533 N.E.2d 264, 266, as follows:
“ * * * Such disputes are properly determined by SERB, which was designated by the General Assembly to facilitate an amicable, comprehensive, effective labor-management relationship between public employees and employers. * * * [Citation omitted.] As long as SERB’S decision on such matters is supported by substantial evidence, it must be affirmed. Courts should not be required to intervene in every factual dispute between contesting parties.”
The review by the court of appeals is confined to the issue of whether the trial court abused its discretion. Lorain, supra, at 261, 533 N.E.2d at 267. An abuse of discretion involves more than an error of law or of judgment; it connotes an attitude on the part of the court that is unreasonable, unconscionable or arbitrary. State, ex rel. Commercial Lovelace Motor Freight, Inc., v. Lancaster (1986), 22 Ohio St.3d 191, 22 OBR 275, 489 N.E.2d 288; Rohde v. Farmer (1970), 23 Ohio St.2d 82, 52 O.O.2d 376, 262 N.E.2d 685. For the following reasons, we hold that the court of appeals improperly substituted its judgment for that of the trial court.
The trial court affirmed SERB’S finding that the sheriff had engaged in unfair labor practices in violation of R.C. 4117.11(A)(1), (3), and (8), which state:
“It is an unfair labor practice for a public employer, its agents, or representatives to:
“(1) Interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in Chapter 4117. of the Revised Code or an employee organization in the selection of its representative for the purposes of collective bargaining or the adjustment of grievances;
(( * * sje
“(3) Discriminate in regard to hire or tenure of employment or any term or condition of employment on the basis of the exercise of rights guaranteed by Chapter 4117. of the Revised Code. Nothing precludes any employer from making and enforcing an agreement pursuant to division (C) of section 4117.09 of the Revised Code.
(t * * *
“(8) Cause or attempt to cause an employee organization, its agents, or representatives to violate division (B) of this section.”
The court of appeals found that: “This court cannot agree that the timing of the revocations [of the two deputies’ commissions] was in such close *507proximity as to warrant an inference of discriminatory intent. * * * ” It also determined that other conduct and statements by the sheriff did not support a finding of anti-union bias.
The findings of SERB were based on specific evidence presented to the hearing officer. The hearing officer’s findings, adopted by SERB, state in part:
“ * * * [I]t is patently clear that the three deputies were engaged in the exercise of rights guaranteed in O.R.C. Chapter 4117. All three deputies filed grievances pursuant to the collective bargaining agreement and submitted the grievances to arbitration. Immediately thereafter, the deputies were notified that their auxiliary commissions were being revoked. The evidence demonstrated that the reasons given for the revocation were pretextual. * * * ”
All evidence upon which SERB’s findings were based is clearly set out in the records of the hearings. The findings of the hearing officer were adopted by SERB in its order of December 22, 1988.
Upon review after remand, the trial court determined that SERB’s orders were supported by “substantial evidence and in accordance with law.” The court of appeals reviewed the evidence and held that the finding of violations was not supported by substantial evidence. It held that because, in its judgment, the evidence was not substantial, the trial court abused its discretion. The fact that the court of appeals viewed the evidence differently than did the trial court does not support the court of appeals’ conclusion that the trial court abused its discretion. A review of the record indicates that the trial court did not abuse its discretion when it determined that the orders of SERB were supported by substantial evidence. For the foregoing reasons, the judgment of the court of appeals is affirmed in part and reversed in part, and the cause is remanded.
Judgment affirmed in part, reversed in part, and cause remanded to the trial court for further proceedings not inconsistent with this opinion.
